A few questions about the control system...

I'm considering starting a software project which would basically offload most of the robot code from the RoboRIO to a sub-connected android device (mostly for speed considerations, I'd like to be able to run robot code much faster than 20Hz)- I have a few questions that need to be answered beforehand however.

1. I know that the driver station only sends packets every 20ms, but are there any control system components (Talons, Solenoids, RoboRIO, etc.) which can only accept/execute inputs at 50Hz? I haven't managed to find any that do, but I figured I'd ask to be safe

2. How fast could the the android and the RoboRIO communicate over usb? Assuming I used something like RIODroid to, for example, send the phone a table of variables describing the state of the robot and joysticks (or vice versa), would there be a significant latency between the two

3. Does WPILib limit code running on the RoboRIO to 50Hz? If so, is there a way around that?
